Lunar Orbit vs Solar System Sim
Price, ratings, monetisation and update history for both games, side by side — with what reviewers say about each.
Lunar Orbit
Guide an asteroid containing life-creating elements to inhabitable planets by manipulating gravity and using black holes. Navigate through space, avoid obstacles, and create new galaxies.
- Physics-based space simulation
- Gravity manipulation
- Black hole navigation
- Obstacle avoidance
- Galaxy creation
- Multiplayer galaxy building

Lunar Orbit is a game that will show you how easy and simple physics works in the space! You control the asteroid. It contains elements that can create life when they interact with water. Guide the asteroid to blue planets to inhabit them. Gravity! Use red planets to adjust the asteroid’s movement. Gravity fields of such planets are very strong! Use them to change the direction of the asteroid. Go around the obstacles and hit the target. But don’t fly to close to the red planet because gravity will drag you in and you will lose a life. Black holes! Sometimes you’ll not be able to go around the obstacles that you see on your way. Use Black Holes! As you enter one of them, you will instantly come out from another. Your speed and direction after the jump will remain the same. Calculate your trajectory smartly and choose the right Black Hole as an entrance. Obstacles Sometimes asteroid belts and other space junk will block your way to the blue planet. If your asteroid collides with them it’ll be destroyed and you’ll lose the chance to create life on the planet. Do your best to avoid them. Join other players from all over the world and create your own unique galaxy.

Zoom from a planet's surface out to distant galaxies, then reshape the whole system with your own hands. Solar System Sim is a real-time gravity sandbox built on Newton's laws and real astronomical data. Every body you add, move or destroy recalculates the orbits of everything else, live. • Smash worlds together: impact craters carve into the surface, firestorms sweep the globe, and glowing debris rains back down. • Build your own universe: add planets, moons, asteroids and comets with their own size, mass and looks, or customise the ones already there. • Land anywhere: drop to a first-person view on any planet's surface and experience its environment. • Sculpt rings: add particle rings and watch gravity shape them in real time. • Witness real eclipses: solar and lunar, with real-world astronomical precision. • Follow comets: watch them streak past and interact with the bodies they meet. • Leave the Solar System: travel to remarkable nearby stars and find them within the Milky Way. • Feel the scale: see the true vastness of space, from a pebble-sized moon to the nearest galaxies. Whether you're here to learn how gravity really works or just to break planets with it, explore at your own pace. Start your cosmic adventure with Solar System Sim.

Verdict
The clearest difference is rating: Lunar Orbit at 5.0 against Solar System Sim's 4.5. Lunar Orbit also leads on in-app purchases (none vs 5) and ads (none vs shown). Solar System Sim's advantage is ratings volume (4.4K vs 2) and update cadence (every 5 days vs every 3 weeks). On price, review sentiment and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Solar System Sim sells 5 one-off in-app purchases. Lunar Orbit asks for nothing beyond the download.
Lunar Orbit holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Solar System Sim has 4.4K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 75% of Lunar Orbit's written reviews are positive against 81% of Solar System Sim's, so the app with the better star average is not the one people write more warmly about.
Lunar Orbit ships an update every 3 weeks, Solar System Sim every 5 days. The most recent releases landed on October 16, 2026 and November 1, 2026 respectively.
